Abstract
The objective of this study was to translate the Ferrans and Powers Quality of Life Index (QLI) into the Indonesian language, considering its cultural and functional appropriateness, and to evaluate its psychometric properties by testing the reliability and validity. A committee approach was conducted to create the Indonesian version of the QLI (QLI-Id) and cognitive interviewing with 15 patients with cancer was conducted to identify potential problems or errors in answering the QLI-Id. A cross-sectional descriptive study was carried out using 236 responses to the QLI-Id questionnaire from patients with cancer; 62 of whom completed the same questionnaire twice within a 3-week interval to verify stability reliability. Confirmatory factor analysis results supported construct validity with model fit statistics for the original single-factor and four-factor structure of the QLI (corresponding to the QLI's total score and four subscale scores, respectively) with some rearrangement of the items within each subscale. Reliability for the total QLI-Id scale was supported by McDonald's Omega of 0.92 and the intraclass/intrasubject correlation coefficient at two time points of 0.86. The strong correlation between the QLI-Id total and the Satisfaction with Life Scale scores and the overall health/QOL domain of the EORTC QLQ-C30 (both r = 0.73) supported its construct validity. This study provides evidence for the reliability and validity of the QLI-Id as an instrument to measure the impact of cancer on the overall QOL of Indonesian patients.
期刊介绍：
Research in Nursing & Health ( RINAH ) is a peer-reviewed general research journal devoted to publication of a wide range of research that will inform the practice of nursing and other health disciplines. The editors invite reports of research describing problems and testing interventions related to health phenomena, health care and self-care, clinical organization and administration; and the testing of research findings in practice. Research protocols are considered if funded in a peer-reviewed process by an agency external to the authors’ home institution and if the work is in progress. Papers on research methods and techniques are appropriate if they go beyond what is already generally available in the literature and include description of successful use of the method. Theory papers are accepted if each proposition is supported by research evidence. Systematic reviews of the literature are reviewed if PRISMA guidelines are followed. Letters to the editor commenting on published articles are welcome.
